First, let me say thanks for WMBurns for all he does for the community. This post is a warning/heads up for new guys running pinout tests on their PCM/ECM. See those three connectors (2 gray, 1 black) above of the PCM? Yeah, they need to be plugged in to each other when the factory manual says "REMOVE PCM." OK, you remove your PCM and then don't reconnect those 3? You will not be able to successfully run your pinout tests if you don't. Just a lesson learned on my part. Hopefully this will help someone. I just got done determining my PCM was fried and my FPDM was ok. I was upgrading my alternator wire to a 4AWG and fried the computer by connecting the negative terminal and THEN reconnecting the positive terminal. I knew better and just wasn't thinking.
